Description

The present invention relates to foldable transport packaging for machine parts, in particular for large roller bearings.

Machine parts and in particular large diameter bearings are usually transported from the manufacturer to the customer, possibly with intermediate storage. Particularly for large diameter bearings with a diameter of at least 500 mm and more, high demands are placed on the transport packaging in order to be able to handle them safely.

It is generally known from the prior art that such machine parts are packaged in individually manufactured disposable boxes, in particular those made of wood. Since such disposable boxes are always designed for the corresponding machine part, differently dimensioned wooden boxes have to be provided in the warehouse. This requires high storage capacities and generates unnecessary costs. Since such packaging boxes are intended for one-time use, they are also not resource-saving.

Proceeding from this, the object of the present invention is therefore to provide improved transport packaging for machine parts, in particular for large roller bearings.

Description of the invention

According to the invention, the object is achieved by a foldable transport packaging with the features of patent claim 1.

The foldable transport packaging according to the invention is intended and suitable for fixing, storing and transporting machine parts and in particular large roller bearings. The foldable transport packaging comprises a four-cornered, preferably square, base plate with at least two on its base surface elongate bearing elements protruding from the bottom surface and elongate fixing rails arranged parallel thereto are arranged and firmly connected to the bottom plate; four wall elements articulated to the base plate, the wall height of which corresponds at most to half the side length of the base plate; and a locking lid.

The foldable transport packaging according to the invention is designed in such a way that it is intended for multiple use and is therefore particularly resource-saving. Because it is foldable, it can be stored in a particularly space-saving manner, which has an advantageous effect on storage capacity and storage costs. In addition, machine parts, in particular large roller bearings of different sizes, can be accommodated by means of the transport packaging according to the invention. This is made possible by the fact that the transport packaging comprises at least two elongate bearing elements and elongate fixing rails arranged parallel thereto, via which the machine part to be packaged can be fixed, for example by means of several tension belts.

Further advantageous refinements of the invention are specified in the dependently formulated claims. The features listed individually in the dependent claims can be combined with one another in a technologically meaningful manner and can define further refinements of the invention. In addition, the features specified in the claims are specified and explained in more detail in the description, with further preferred configurations of the invention being presented.

In principle, the transport packaging according to the invention can comprise at least two bearing elements protruding from the bottom surface and at least one elongated fixing rail arranged parallel thereto, on which the goods to be packaged can be placed in the transport packaging and fixed with it. In this embodiment variant, the bearing elements are arranged running parallel to the side wall elements. The at least one fixing rail is then preferably arranged between the at least two bearing elements. In a further advantageous embodiment variant, the transport packaging according to the invention can also comprise at least three bearing elements protruding from the bottom surface and in each case an elongate fixing rail arranged parallel thereto. The at least three bearing elements and fixing rails are then preferably star-shaped with the same distance from one another on the floor surface arranged in such a way that one of the bearing elements is arranged parallel to one of the side wall elements and two of the bearing elements are arranged to run diagonally to the side wall elements.

In a particularly advantageous embodiment variant, the base plate comprises four fixing rails arranged diagonally to the side walls, each fixing rail being surrounded at least partially, more preferably completely, by two bearing elements arranged parallel to one another along its longitudinal extension. The fixing rails are connected to the base plate in a non-positive manner in such a way that they can each withstand a maximum load of 1500 kN. Such a connection can be achieved, for example, by frictional locking.

The bearing elements can have an anti-slip coating, for example made of rubber.

Various rotationally symmetrical machine parts of different sizes, such as large roller bearings with an outer diameter of, for example, 1800 mm or smaller and/or their components, such as a roller bearing inner or roller bearing outer ring, can be placed on the elongated bearing elements and fixed, for example, by means of tension belts via the fixing rails.

In an advantageous embodiment variant, the base plate has a peripheral side wall which is formed from at least four side wall elements which are firmly connected to the base plate. In this context, it is particularly advantageous for two side wall elements arranged opposite one another to have a side wall height that is different from the other two side wall elements lying opposite one another, so that two of the total of four side wall elements have a first side wall height and two side wall elements have a second, greater side wall height. In this case, the difference in height advantageously corresponds at least to the material thickness of the wall elements.

In an advantageous further development, the four wall elements which are articulated to the base plate are articulated to the base plate via the respective side wall elements. It is particularly advantageous here that the wall elements are connected in an articulated manner to the base plate, in particular the side wall elements, via hinges, in particular two-part hinges. the Hinges represent a particularly favorable solution for making the transport packaging foldable. The two-part hinges have the additional advantage that the wall elements can be removed. This facilitates accessibility when securing the goods to be packaged, so that the packaging process as a whole is significantly simplified.

In order to achieve the lowest possible height of the transport packaging when folded, the respective wall elements should be able to be arranged as flat as possible one above the other and parallel to the base plate. It is therefore advantageously provided that those two wall elements which are articulated to the two side wall elements which have the second larger side wall height extend over the entire side length of the base plate.

The lateral edges of the two wall elements are preferably reinforced by means of metal corner profiles.

So that the transport packaging has the required dimensional stability when assembled, each of the wall elements and, if applicable, the closure lid comprises a number of elongated depressions via which the wall elements can be detachably connected to one another and, if necessary, to the closure lid using clips.

In order to further increase the dimensional stability of the transport packaging, the wall elements can also be connected to one another using L-shaped clip-on profiles. The transport packaging therefore advantageously includes four such clip-on profiles, via which the wall elements can be connected to one another.

Furthermore, the transport packaging can comprise a number of foot elements on the base plate, so that the transport packaging can be driven under by a forklift truck and stacked on top of one another, for example.

Due to the size of the cap, it may be necessary to reinforce it. The closure cap can therefore advantageously comprise two or more elongate reinforcement ribs, which give the closure cap the necessary stability. These are preferably offset from the foot elements in order to simplify stacking on top of one another. Furthermore, a support element arranged centrally on the base plate can be provided, via which the closure cover can optionally be additionally supported. To stow all components in one unit when folded can, the support element is preferably designed to be foldable, so that it can be stored particularly easily on the floor surface in the folded state.

In the built-up form of the transport packaging, the support element can be slipped over a storage frame arranged centrally on the base plate. The storage frame thus serves as a base for the support element. In the collapsed state of the transport packaging, the storage frame advantageously serves as a storage box for the various loose parts of the transport packaging, such as the clips and/or the clip-on profiles.

The transport packaging is preferably made of wood, in particular of screen printing boards, with other materials such as plastics also being conceivable and possible.

In a further aspect, the present invention also relates to the use of the foldable transport packaging according to the invention for fixing, storing and transporting machine parts, in particular large roller bearings.

In figure 1 an embodiment variant of the foldable transport packaging 1 according to the invention is shown in assembled form in a first perspective representation. The foldable transport packaging 1 is intended and suitable for fixing, storing and transporting machine parts and in particular large roller bearings with an outside diameter of at least 500 mm and more.

The foldable transport packaging 1 comprises a quadrangular base plate 2 which is square in the present case and is delimited by a peripheral side wall 3 . The base plate 2 has the dimensions 1800×1800 mm in the variant shown here and consists of a 15 mm thick screen-printed plate. The peripheral side wall 3 is formed from four individual side wall elements 4, 5, 6, 7, which are each firmly connected to the base plate 2, for example butt jointed. Of the total of four side wall elements 4, 5, 6, 7, two oppositely arranged side wall elements 4, 5 each have a side wall height that is different from that of the other two side wall elements 6, 7, which are respectively opposite one another. How based on figure 1 recognizable, the two side wall elements 6, 7 have a first side wall height and the two side wall elements 4, 5 have a second, larger side wall height.

Again figure 1 Also removable, the base plate 2 has on its base surface 8 a plurality of elongate bearing elements 9 protruding from the base surface 8 and elongate fixing rails 10 arranged parallel thereto, which are firmly connected to the base plate 2 . The total of four fixing rails 10 arranged diagonally to the side walls 3 on the floor surface 8 have a length of 500 mm in the embodiment variant shown here. The fixing rails 10 are connected to the base plate 2 in a non-positive manner in such a way that they each withstand a maximum load of 1500 kN. Each of the fixing rails 10 is surrounded along its length by two bearing elements 9 which are arranged parallel to one another and are provided with an anti-slip coating 11, for example made of rubber ( 2 ). Rotationally symmetrical machine parts of different sizes, such as large roller bearings with an outer diameter of, for example, 1800 mm or smaller and/or their components, such as a roller bearing inner or roller bearing outer ring, can be placed on the elongated bearing elements 9 . The respective item to be packaged can then be fixed over the fixing rails 10 and secured against slipping, for example by means of four tension belts (not shown).

The foldable transport packaging 1 also comprises four wall elements 12, 13, 14, 15 which are articulated to the base plate 2 and which, in the embodiment variant shown, are articulated to the side wall elements 4, 5, 6, 7 of the base plate 2 via separable two-part hinges 16. As a result, the wall elements 12, 13, 14, 15 can be folded in, so that the entire transport packaging 1 in a folded state has only 25 to 30% of the volume compared to the assembled form. On the other hand, the wall elements 12, 13, 14, 15 can be removed via the separable hinges 16, as is shown in figure 3 is indicated. This facilitates accessibility when securing the goods to be packaged, so that the packaging process as a whole is significantly simplified.

As further based on the illustration in figure 1 As can be seen, the two wall elements 12, 13 arranged opposite each other extend over the entire side length of the base plate 2 and are articulated to those side wall elements 4, 5 which have the greater side wall height. Accordingly, the two remaining wall elements 14, 15 have an extent that is reduced by the material thickness of the wall elements 12, 13 and are the same as those Side wall elements 6, 7 articulated, which have the smaller side wall height. The height difference between the two side wall heights 4, 5, 6, 7 also corresponds to the material thickness of the wall elements 12, 13, 14, 15. This means that the individual wall elements 12, 13, 14, 15 can be folded up particularly flat, as shown in figure 8 emerges.

Furthermore, based on figure 1 recognizable that the lateral edges of the two wall elements 12, 13 are reinforced by means of metal corner profiles 17. In addition, each of the wall elements 12, 13, 14, 15 and the cover 18 (see 8 ) Several elongated depressions 19, via which the wall elements 12, 13, 14, 15 can be releasably connected to one another and to the closure lid in the assembled form by means of clips 20. How based on figure 1 recognizable, each of the wall elements 12, 13, 14, 15 has seven depressions 19 each.

To further stabilize the wall elements 12, 13, 14, 15 in the assembled form, two wall elements 12, 13, 14, 15 are additionally connected to one another in the corner regions via L-shaped clip-on profiles 21.

Furthermore, the base plate 2 has three foot elements 22 on its side opposite the base surface 8, over which the transport packaging 1 can be stacked. The spacing of the foot elements 22 from one another is selected in such a way that the transport packaging 1 can be driven under, for example by means of a forklift.

In order to support the closure lid 18 , the transport packaging 1 also has a support element 23 arranged centrally on the base plate 2 . In the present case, this is also designed to be foldable, so that it can be stowed away in the folded transport packaging 1 to save space (see FIG figure 3 ). In the assembled form, the support element 23 is slipped over a storage frame 24 arranged centrally on the base plate 2 . The storage frame 24 serves on the one hand as a basis for the support element 23. In its secondary function, the storage frame 24 serves to store the loose parts of the transport packaging 1, in particular the clips 20 and the clip-on profiles 21.

In figure 2 is the in figure 1 illustrated embodiment shown from the top view. In particular, the four diagonally arranged fixing rails 10 can be seen, which are each surrounded by two parallel bearing elements 9 along their longitudinal extent.

figure 3 shows a representation of the transport packaging 1, in which the wall elements 12, 13, 14, 15 are removed. For this purpose, the various brackets 20 and the clip-on profiles 21 have been removed. By sliding the wall elements 12, 13, 14, 15 along their longitudinal axis, they can be removed due to the separable, two-part hinges 16.

figure 4 shows that figure 3 enlarged corner area A, on the basis of which the two-part hinges 16 and the different heights of the side wall elements 3 can be seen.

figure 5 shows the in figure 1 illustrated embodiment of the transport packaging 1 in a lateral view with the closure lid 18. As in particular based on figure 5 recognizable, the closure cover 18 comprises two elongate reinforcement ribs 25 which are arranged offset to the foot elements 22 . This makes it easier to stack the transport packaging 1.

In figure 6 the transport packaging 1 is shown in a sectional view according to section plane AA. The support element 23 , which is put over the storage frame 24 and serves to support the closure lid 18 , can be seen here in particular.

In figure 7 and 8th is the transport packaging 1 once in an assembled state ( figure 7 ) or shown in a collapsed state ( figure 8 ). The transport packaging 1 was largely made of screen printing plates with a thickness of 15 mm and, in the embodiment shown here, has the dimensions 1800×1800×900 mm when assembled and 1800×1800×270 mm when folded.
